Re: Not Necking Celery
Here's an attempt at answering the question:
"As the comet nears perihelion and becomes increasingly active, it is likely to start throwing off boulder-sized chunks. It might even split in two, although that is regarded as unlikely. One thing we know about comets, though, is that they tend to do the unexpected.
"Philae, about the size of a small refrigerator, could find itself blown out with some of these outgassed and entrained materials. To be lost from the comet nucleus, this would require ejection at several meters per second. But that would be at the large end of sizes, and unless the comet catastrophically disrupts, Philae is likely to stay put.
"Being denser than the cometary materials, Philae's fate might instead be to become increasingly buried beneath all of this mobilized debris, kind of like a snowmobile abandoned in a snowstorm."
Grain of salt, etc.
